To a/ZZ wiwi/n, t may concern:

Be it known that LCHnnLns H. Si-mrrnn,

a citizen of the United States, residing in the city of Rockford, in the county of Vinnebago and State of Illinois, have invented anew and useful Retouching-"lachinc, of which the following is a speciiication.

This invention relates to that class of machines known as retouching-machines5" and its object is to produce a machine capable of.

use mainly in the fine arts for the purpose of retouching crayonings, negatives, and other work requiring retouching to produce the desired effects. For this purpose l have designed and constructed the machine represented in the accompanying drawings, in which- Figure l is a side elevation, showing the parts in position as a rotary machine. Fig. 2 is also a side elevation, showing the opposite side to that shown in Fig. 1. Fig. 3 is an edge elevation. Fig. 4 is a plan view of head end. Fig. 5 is a transverse section on dotted line @c on Fig. 2. Fig. Gis alengthwise central section on dotted line y on Fig. 4. Fig. 7 shows the parts adjusted in position to be employed as a reciprocating machine. FiO. S shows the parts adjusted in position to be employed as a combined rotary and reciprocating machine. Fig. 9 is an enlarged lengthl wise central section on dotted line y, Fig. 4.

In the figures, A represents a supporting.

frame, rectangular in outline form, and of proper dimensions to support an electro-magnetic engine of a suitable capacity. Vithin this rectangular frame is mounted an electro` magnetic engine of one of the well-known forms, consisting of the temporary magnets B, of ordinary construction, fixed in position on the lower end beam of the frame, preferablyv with the axis of the cores in the plane thereof.

At a and a are represented binding-posts, insulated from the supporting-frame by nonconducting bushings a and a. These posts receive the'ends of the wires coiled upon the magnets.

At b is represented a tubular shaft supported to revolve between the magnets in the plane of their axis, having a footjournal of conic form supported to revolve in a ccnic seat in a bearing, b, having a screw-thread connection with the supporting-frame, by which itis made adjustable, and is provided with a jam-nut, b, to fix it in position when adjusted. This tubular shaft is also supported 55 to revolve in a bearing, c, having a screwthread connection with the supportingframe in the side thereof opposite to the bearing b. This bearing c is alsoprovided with a jamnut, c, by which to fix it in position when ad-v 6o j Listed, and its inner end is produced in hollow conic form to furnish an end bearing to the tubular. shaft. The tubular shaft at its junction with its bearing c is provided with a collar or au enlargement, c, produced in conic 65 form, to engage the conic-formed end seat in the bearing c. At C is represented an armature of proper dimensions, having its center portion provided with a hub, G', bored to receive the tubu- 7o .lar shaft b, on which it is mounted in position torenolve therewith in a plane at right angles to the axis of the cores of the magnets a suitable distance fromtheir polar ends. The outer portion of the hub Cis produced in disk form, 7 5 as at 0', having segments cut from its opposite sides on an angle at about fortyiive degrees relatively with a radial line passing through the lengthwise center of the armature, producing a eut-off cam which, in con- 8o nection with a cut-off spring, d, serves to make and break the circuit twice in each revolution of the armature. This cut-off spring is fixed at theV point d to the side beam of the sup porting-frame, from which point it extends S5 transversely toward the center thereof, over the cut-off cani.

At c is represented a circuit-closing screw supported in the axial center of the insulated bindingpostc, having a screw-thread con- 9o nection therewith, by which it is made adjustable endwise. This circuit-closing screw is-designed to engage a stud, d, projecting from the inside of the eut-off spring, and, in connection with the cam 0', serves to make 95 and break the circuit to impart a rotary movement to the armature.

At D is represented a clutch-head of collar form, fixed to the project-ing end of the tubular shaft to revolve therewith. One side of roc this clutch-head is slotted radially in the lengthwise direction of its axis, to receive a lever clutch-arm, 7.1. It is also provided on one side with an anti-friction wheel, c, to revolve on ajournal-support, having its periphery rising above the outer end iaee of the head.

At c is represented a center shaft, supported in the axial center of the tubular shaft in the end bearings thereof in a manner capable o1' a free endwise movement, and to permit an independent rotary movement of the tubular shaft. This shaft c within the tubular shaft is surrounded with a compression spiral spring, '/zf, having a foot-support, i, ol collar i'orin iixed on the shaft, and its opposite end rests against the clutch-head D on the outer end ofthe tubular shaft.

At 7i" is represented a disk-formed cam, having its inner face produced in corrugations radiating from its axial center. This disk-formed cam has a screw-thread connection with the shai't c, by which it is made adj ustable thereon to increase or lessen the holding force of the spring 71 and when adjusted is fixed in place by means ol' a j ani-nut, L.

At i is represented a thumb-nut fixed on the extreme outer end of the shaft e, by means of which it may be rotatedin its screwconnection with the disk-cam for the purpose i of adjustment.

At k is represented a clutch-latch of blade form, having a pivotal connection at 7.1 with the disk-cam in position to enter the radial slot in the clutch-head when the latch is turned in a position parallel with the shaft, as shown in Figs. l, 2, 6, 8, and 9, and serves to connect the center shaft, c, with the tubular shaft b, to cause them to revolve together. This pivoted clutching-latch 7.: is capable et' adjustment to a radial position, as shown in Fig. 7, in which position its free end will engage the adjustable support et' the anti-friction wheel It, to prevent rotation of the ccnter shali't.

At 7.1 is represented a plate-spring fixed to the outer face of the disk-cam, with its free end overlapping` the pivoted end of the clutching-latch in a manner to hold it in its open or closed position. From this construction, and with the clutching-latch in its open position and the parts properly adjusted, it will be seen that the action of the spring 7L within the tubular shai't will operate to hold the diskcain in contact with the anti-friction wheel c on the clutch-head, the rotations of which will impart an endwise reciprocating movement to the center shalt.

At Z is represented a tubular support, on the side of which the anti -friction wheel Zz is mounted to revolve on a suitable journal-support. y

At Z is represented a thumb-screw passed through the axial center of 'the tubular support, and is provided with a collar, Z, to freely enter the enlarged chamber of the support. This thumb-screw within the chamber of the support is surrounded with a compression spiral spring, Z", having one end thereof resting aga-inst the end of the chamber and its other end against the collar on the screw. This support is adjustably iixed on the supporting-frame by means cfa screw-thread connection of the thumb-screw Z therewith in such position thereon that the wheel 7; will engage the corrugated inner face of the diskcani when adjusted for the purpose. The base rim oi' the tubular support Z is groovcd on its periphery to receive a guide-bar, in, iixed in the frame in a manner to permit of an endwise movement o1' the tube and prevent rotary movement thereol. By this construction and arrangement of the parts, with the clutch-blade engaged with the clutch-head and the anti-friction wheel 7.1 adjusted to engage the disk-cam, it will be seen that a rotary movement ol' the armature will impart a rotary and reciprocating movement to the center shaft. The object ol' the spiral spring Z' in the tubular support Z is to permit the tubular support to yield slightly under the stroke oi" the cam in its rapid revolutions over the anti-friction wheel 7.1, mounted on the tubular support, to relieve the concussion or jar.

At E is represented a hand portion ot' tubular form? preferably or' non-conducting material, having a suitable connection with 'the supporting-frame-iii this instance by means of the screw-threaded i'errule F, having' a screw-threaded connection with the hand por tion E, and with the screw-threaded bearing b ot' the tubular shal't. The i'ree end of this hand portion is also provided with. a i'errule, H, having an axial opening to serve as a hearing to an inner pencil-tube.

At a is represented a 1' encil-receiving tube, having its inner end screw-threadcd to receive the screw-threaded end portion, a, ol" the center shaft, on which the tube may be adjusted endwise, and when adjusted is lixed in position by means of ajani-nut, n". This pencilreceiving tube is .'Iitted to rcvolveifreely in the end bearing in the ferrule Il, and is also eapable of an endwise movement therein. The end portion of this pencil-receiving tube n projects from J[he free end of the hand portion, and its projecting end is provided with a pencil-holding device, aim-in this instance substantially such as are found in the trade and are -in common use, but maybe any ol" the known varieties capable of use in this connection, for the purpose oi" holding the pencil o, which may be ol:` any of the known varieties capable of use in the retoucher.

At p is represented a wheel el' disk form, having a screw-threaded connection with the projecting end of the pencil-receiving tube, near the free end of the hand portion, in a convenient position for the operator to employ his linger to start, stop, and control the rotary and reciprocating movement of the pencil.

At s is represented a binding-post, with IOO which one of the poles of the battery is connected bymeans of a wire, s. This bindingpost is supported on the frame, but is insulated therefrom by means of the non-conducting bushing d, inserted in the frame, and the binding-post is supported therein.

At t is represented a binding-post fixed in the metallic supporting-frame, and is connected by a wire, t', to the pole of the battery opposite the pole connected to t-he bindingpost s, and serves to connect the battery and machine in complete circuit.

From the foregoing it will be seen that I have produced a retouching-machine in which the pencil is capable of a rotary movement, or a reciprocating movement, or a combined rotary and reciprocating movement.

In the use of my improved retouching-machine the pencil or crayon is properly adj usted and fixed in the machine; its free' projecting end is then properly pointed, being reduced by grinding or otherwise, which ts the machine for use, to be employed by the operator in the manner of using pencils or crayons in retouching negatives, producing, retouching, and finishing crayons in all varieties.

I claim as my invention- I. rIhe combination,with the tubular shaft,
